magnetic field (H)

Magnetic fields (H-field) occur where current flows through a conductor, i.e. in every conductor through which current flows.

The strength of the magnetic field depends on the current strength and - in the case of coils - on their number of turns. The magnetic field strength is given in amperes per meter (A/m) and the magnetic flux density in tesla.

Magnetic field lines by induction

The field lines of the magnetic field form a circle around the current-carrying conductor. The direction of the magnetic field lines, which are oriented perpendicular to the current flow, depends on the direction of the current and is perpendicular to it.
